Definitions

  • the battery pack 110 is configured to power one or more electronic components of the aircraft - it may be used to provide electric power to one or more electric propulsion systems (not shown) of the aircraft 100, and it may also be used to provide electric power to any other electric components onboard the aircraft 100.
  • the term "battery pack” may refer to one or more individual batteries contained within a single piece or multi-piece housing, where the individual batteries are electrically interconnected to achieve a desired voltage and capacity for a particular application.
  • the computing system 240 may receive a user input indicating that the cabin temperature is to be warmed.
  • the user input may be flipping of a switch or pressing of a button in the aircraft 200 indicating that the cabin 205 is to be warmed.
  • the computing system may receive measurements from the cabin temperature sensor 230 and the battery temperature sensor 232. If the measurements indicate that the battery temperature is higher than or equal to the cabin temperature, then the computing system 240 may enter into a heating mode, where it may operate the valve 228 such that fluid is circulated to the heat exchanger 222 via the thermal loop 221. Given the higher temperature of the battery temperature, the fluid may be warmer relative to the cabin 205.
  • the cabin thermal management system 220 may operate the valve 228 to transfer thermal energy from the fluid in the thermal loop 221 to the cabin 205 for situations where the battery pack 210 is at risk of overheating, regardless of the cabin temperature or whether the user input indicated that the cabin is to warmed or cooled. Such examples may be used to draw heat away from the overheating battery pack 210.
  • the thermal loop 221 may be coupled to similar tubing disposed in seats of the cabin 205, thereby allowing fluid to circulate in the tubing of the seats.
  • the cabin thermal management system 220 may be used to cool or warm the seats of the cabin 205 in a similar manner as described above with respect to Figures 3-6 .
